GOVERNOR FOR WATER-DRIVEN MOTORS.

Specification of Letters Patent. Patented Feb. 14, 1922.

Application filed March l29, 1920. Serial No. 369,612.

which the following is a specification.

This invention relates to devices for controlling the speed of water driven motors, such as water wheels and the like, and has for one of its objects to simplify and improve the construction and increase the efiif ciency and utility of devicesof this character.

Another object of the invention is to provide a device of this character including a waterdriven motor, flow controlling means, electrically operated means for actuating the flow controlling means, a governor operative by the motor, and means whereby the speed of the motor controls the How controlling means.

W'ith these and other objects in view, the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims, and in the drawings illustrative of the preferred embodiment of the invention.

Figure 1 is an elevation partly in section, of the improved device.

Figure 2 is a plan View 9of the parts shown in Figure 1,

Figure 3 is an enlarged sectional detail on the line 3-3 of Figure 1 looking in the direction of the arrow, y

Figure 4 is an enlarged sectional detail on the line 4-4 of Figure 1.

The improved device may be applied without material structural change to water driven motors and the fio-w controlling means associated therewith, of any of the various forms in use, and it is not desired to limit the invention in any manner in this respect, but for the purpose of illustration a conventional motor of the turbine type, represented as a whole at 107 and a conventional flow controlling mechanism represented as a whole at 11. The intake conduit is represented at 12, the discharge or tail conduit at 13.

The drive shaft of the motor is represented at 15 and includes a belt pulley 16.

A governor device is located adjacent the belt pulley and includes a sleeve 17, a belt pulley 18 rotative on the sleeve and around which a belt 19 from the pulley 16 on the motor shaft 15 operates. The governor like-l wise includes a drive shaft 20 'slidable kthrough the sleeve 17 and carrying the usual arms 21 having the usual governor balls 22 at their free ends. The pulley 18 is coupled to the arms 21 by links 22, as shown.

As its lower end shaft 20 is provided with a disk 23 which is rotatable with the shaft and movable therewith through the jacent the How controlling mechanism 11 is a frame-26 including guide members 27 and bearings 28, the latter rotatively supporting a belt pulley 29 having an internally threaded hub 30.

Slidable ink the guides 27 is a cross head device 31, and carried by the cross head is a bar 32 held from rotation in the cross head and threaded as shown at 33 to engage the threaded hub 30 of the belt pulley 29. By this means when the pulley 29 is rotated the bar 32 will be moved longitudinally and the cross head 31 correspondingly moved in the guideways 27. The gate actuating mechanism includes an operating member 34 pivotally connected to the bar 32 by a rrod 35.

Means are provided for actuating the belt pulley 29 consisting of a relatively small electrically driven motor, represented conventionally at 36, and including a shaft 37 having a belt pinion 38 from which a belt 39 leads over the pulley 29.

The reversing devices are connected to the contacts 24 and 25 and to thev disk 23 by conductor wires indicated respectively' at 4243 and 41.

Means are thus provided for setting" the gate mechanisml to any required degree to permit a normal flow to the motor 10, inde endently of the influence of the controlling motor 36, and so lone` as the speed of the water driven motor is normal the disk 23 will be maintained in neutraliposition, or out of engagement with both `of the contracts 24 and 25.

If the flow through the'gates of the motor l0 increases, the speed of the latter will be corres ondingly increased, and the speedvof) the-goVernor'Wi'll also be correspondingly increased and cause the weighted arms 2lto 4 rise and depress the shaft 2O and its disk 423, `and zcause the latte-r to engagethe contact V25 and close a circuit through the'ldisk and themotor 36, and rotate the` sha-lt 3T inta directionto cause the threaded bar 32 respondingly reverse thegmotionl of theba'r 32 and open the `gates of the kmotor` 10 and permit more Water to -lou7 ytherethrough and thus lincrease lthe speed of `the ,Water driven motor. y t

'The motion of the motor 1.0 is thus automatically controlled and maintained at a uniform speed.

` The preferred yembodiment of the invention'is disclosed in the drawings and set forth in the speciiications, but it will be understood that any modifications within they scope offthe claims may be made in the construction Without departing from the principle of the invention or sacricing any.,ofitsadvantages. Y
